The dataset itself is available at the bottom of the page - "Download the data." This page is a competition among data analysts/mathematicians to produce the most accurate predictive model, based on historical hospital admittance data, for finding people likely to enter a hospital in the next year - Giving preventative medicine a leg up by statistically determining the at-risk patients and decreasing the cost of care. Super cool!

"anyqs" Where are they getting the data for the music? Most listened to on radio? Pandora? Youtube searches? Also, what does the size of each square represent?

This is a really cool visualization. I spent some time playing with the different layers and you can really see the different trends in music throughout history. Most are what you would expect, i.e. predominance of jazz and classical music pre-1950, rock and roll taking over after about 1950. I'm curious about how the genres were designated. Sorting music into genres isn't always so neat since there can be overlap. For example, James Brown is listed under funk but he is also "the godfather of soul". It would be interesting to know some demographic information such as the age groups that tend to like certain music. anyqs

anyqs Is there any definition to the points above and below the "x-axis"? Were these the Top 10 chart hits for these various years, or where did these songs come from? In my opinion, there is a strong lacking of representation for popular country in recent years, as country music has gained popularity in the past decade and a half, or so. Finally, where are the definitions for these genres coming from? For example, I'm not entirely sure I'd classify Rihanna as an R&B musician.

*By having the size of the dot represent the amount of times it was favorited and its location on the y-axis represent its popularity aren't you factoring in how well liked the song is multiple times? How do you differentiate between pop and vocal pop, or any two genres for that instance? Can a song be counted in multiple genres? anyqs

That's a pretty nice segmented bar chart on the right.

anyqs How many people did they sample, and did they just find them at bars?

There seems to be a trend that the lower income bracket prefers beer and the higher income bracket prefers wine. What I find interesting is that all incomes prefer liquor equally. I wonder why this is true? Also it says that last year they surveyed people about their preferences but where did they get the data for previous years? Lastly, it states no information on how reliable the data is or what method of sampling was used. anyqs

anyqs: I would like to know how big the sample size was. Also, how many of the participants are actual college students? I'd like to see the data on purely college students.

anyqs: I would definitely like to see some more info on this, the things mentioned above as well as what N/A actually means. Does it mean non drinker? Also I'm guessing that they did not poll anyone under 21. I think there's more non-drinkers than drinkers under 21 but including that group would certainly change things (most likely lessen the wine numbers). Finally, it's not a big deal but the 36% for beer in 2011 appears higher up on the graph than the 36% in 2005.

Moore's law describes a long-term trend in the history of computing hardware whereby the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years.
